BUTTON-SETTING MACHINE.

SIECIFICATION forming part of Letters Patent No. 394,546, dated December 11, 1888.

Application filed September 2l, 1888. Serial No. 286,009. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE H. TAYLOR,of Lynn, county of Essex, and State of Massachusetts, have invented certain new and useful Improvements in Button Setting Machines, of which the following is a specification, reference being had to the drawings accompanying and forming a part hereof, in which Figure l is a side elevation of a hand-machine embodying my invention, with the operating-handles broken away. Fig. 2 is a front elevation of the same. Fig. 3 is a vertical section of the operative parts of my device, showing the jaw open. Fig. et is a similar view showing the jaws closed in the operation of setting a button. Fig. 5 is a perspective of the driver detached and of a button and fastener in the relative position which they occupy when the button is being set.

The chief object of my present invention is the production of a simple and effective device which may be applied to button-setting machines, which shall operate to deliver the buttons and attached 'fasteners to the driver; and it consists, chieiiy, in the automatically operating lever devices on the face of the guide-tube and their construction and arrangement, as hereinafter set forth.

I will describe my invention as embodied in the hand-machine for setting buttons shown in the drawings; but, as will be obvious, it may be equally well adapted to machines operated by power.

The upper and lower jaws of the device are shown at A and B, respectively, and they are caused to approach each other by closing the handles A B', which are pivoted at C in the well-known manner. The end of the lower jaw is provided with a die, a, secured in place by a set-screw, l), from the under side of the jaw, as will be clear from Figs. 3 and 4.. The prongs of the fastener, after passing through the material, are forced against the die'a,l

which is provided with depressions c, Fig. 2, which receive the ends of the prongs and cause them to turn and clinch. The end of the upper jaw, A, is enlarged, as shown, and is slot.- ted vertically to receive the block or piece d, which supports the staple guide-tube D, and which is secured thereto by screws e. The

block d is slotted at f, as shown in Figs. 3 and 4, to receive a pin, g, which serves to secure the block d and guide-tube in position and at the saine time admit of their vertical movement relatively to the jaw A and also of their lower portion bein swung slightly outwardly away from the jaw on the pivot or pin C, as a center, as shown in Figs. l and f3.

The guide-tube D may be of any length desired to accommodate a number of buttons and their fasteners, and is provided throughout its length with a slot or way, h, of wellknown form, to receive and guide the fasteners, and with an open slot, j, for the eye of the button, as shown. The lower end of the guideway D has an open slot, cut vertically in the rear thereof, to receive the neck lc of the driver E, and an oblique slot, I, opening into the staple-passage h, as shown in Figs. 3 and i, to receive the operating end of the driver E. This slot I receives the end of the driver as the guidetube D is forced downwardly by the spring m, and leaves the fastener passage or way clear, as shown in Fig."3, so that a fastener may drop down into position below the driver ready to be set. As the guide-tube is forced upwardly by the pressure of the lower jaw in setting a button, the slot l acts as a cam, forcing the guide-tube back and carrying the end of the driver into the fastener way or passage behind the fastener. The driver E is rigidly secured to the under side of the jaw A by a screw, n, as shown. The end of the driver is forked or branched, as shown in Fig. 5, the notch or recess between the branches being for the purpose of allowing' the eye of the button to pass it easily as the button and fastener are going down the guidetube into position at the lower end thereof, as will be clear from Fig. The spring m may be fastened in any convenient way to the jaw A, and bears at its forward ends on pins set in either side of the guide-tube, as shown in Fig. l.

For the purpose of keeping the button and its attached fastener, which are in position at v the lower end of the guide-tube, from falling out of the tube, I provide a spring, p, which is secured to the side of the guide-tube at the lower end thereof, the end of the spring being turned and inserted in a hole which opens IOO into the fastener' passage or way 7L, thus permitting the inwardly-projecting end of the spring to project slightly into the passage 7L, so as to come in contact with one side of the fastener sufficiently to hold it from dropping out of the tube, and at the same time allowing it to be forced out by the4 driver. As the buttons and fasteners are liable to fall out of the other end of the guide-tube in case that end be turned down, as would be likely to happen with hand machines, I provide a spring, q, at the end of the guide-tube, similar to the spring p, secured in the same way, (see Figs. 1 and 2,) and operating, as does the spring p, to present a slight resistance to the passage of the fasteners.

For the purpose of allowing the buttons and their attached fasteners to pass one at a time down to the lower end of the guide-tube below the driver, I have provided two levers which operate automatically as the guidetube moves when the jaws are brought together. One of these levers d is pivoted to a lug, b', secured to one side of the guidetube. (See Fig. 2.) This lever is bent, as shown, so that it passes across the face of the guide-tube in the path of the buttons, and at the other side of the guide-tube'isbent on itself, as shown atd, Fig. 2. of the lever 0, ashorter right-angled lever, f is pivoted at g. The free end of the lever f also crosses the face of the guide-tube in the path of the buttons parallel to the lever a and at a distance from the lever d just sufficient to accommodate one button. As the jaws of the machine open, allowing the guidetube D to be forced downward, the lowermost lever, a', is swung outwardly, allowing the single button, which is between the levers, to drop, and simultaneously, or substantially so, the upper lever, f is thrown against the face of the guide-tube, preventing the remaining buttons in the tube from falling. This outward movement of the lever a is caused by a projection, h', on the lever (see Fig. l) coming in contact with a stop, j', which is fast on the jaw A of the machine and is therefore stationary while the guide-tube moves, and the inward throw of the upper lever, f', is caused by the spiral spring 70, which is fast at one end to the lever and at the other to a pin in the side of the guide-tube. When a button is being set, the movement of the guidetube D is reversed. A projection, Z', on the lever f (see Fig. l) comes in contact with the stop m', which is fast on the jawAon the opposite side of the jaw from the stop j', and which, like the stop j', remains stationary while the guide-tube moves. As the guide- In this bend d tube moves up relatively to the jaw A, freeing the projection l1. from contact with the stop j', the spring k acts to pull the lever a down against the face 0f the guide-tube, and the further movement of the guide-tube brings the projection Z into contact with the stop m', thus throwing lever f away from the face of the guide-tube and permitting the buttons to drop until the lowermost button is in contact with the lever a.

The operation, as above described, will be clear from the drawings, more particularly Figs. 3 and 4, which show the levers a f in both positions-that is, when the jaws are closed and the lever d is holding the buttons, Fig. 4, and when the jaws are open and the lever f is holding the buttons, Fig. 3.

The slight curvature or rounding of the rear face of the block d (shown in Figs. 3 and 4) is for the purpose of allowing the lower end. of the block and guide-tube to be thrown outwardly under the downward and outward pressure of the springs m.

Vhat I claim isl. In a button-setting machine having a guide-tube mounted on the jaw of the machine and movable relatively to said jaw, thel combination, with said guide-tube, of two levers, as c f projecting across the face thereof, one of said levers being pivoted at one end to the guide-tube and the other of said levers being pivoted to the free end of the first lever, and stops, asj m', fast to the said jaw of the machine, whereby as the guidetube is moved relatively to said jaw the levers are operated, substantially as shown and described.

2. In a button-setting machine, the combination, with the driver, of a slotted block, as rl, pivoted to the jaw of the machine above the driver, a guide-tube secured to said block, and a spring which actuates the guide-tube and block in one direction, substantially as shown and described.

3. In a button-setting machine, the combi,- nation, with a driver, of a vertically-movable guide-tube for the buttons and attached fasteners, said guide-tube being slotted vertically at its lower end to receive the neck of the driver, and having an oblique slot opening into the fastener-passage to receive the end of the driver and allow a button and fastener to pass below the driver when the guide-tube is swung outwardly, substantially as shown.

and described.
